GREATEST COMMON FACTOR

Factoring FactoringFactoring- to factor an algebraic expression we change the form of an expression and put it in factored form. It is the reverse of using.

Recall: By the distributive property, we have x ( x + 2 ) = x² + 2x Now we’re given a polynomial expression and we want to perform the “opposite” of the.

Presentation transcript:

Factoring EX: (22x – 4) = 2(11x – 2) Factoring is the opposite of distributing (rainbow arrows). It brings a number out of the parenthesis instead of putting it in. EX: (22x – 4) = 2(11x – 2) expanded form factored form

Going from Expanded to Factored form: Find the Greatest Common Factor between all values in the expression Put the GCF outside of ( ) Example: the GCF of 3 and 18 is 3.

Take the first value and divide it by the GCF (3x + 18) 3x divided by 3 = 1x Take the second value and divide it by the GCF (3x + 18) 18 divided by 3 = 6 Rewrite expression with the factor out of () 3(x + 6)

Example Factor (16x + 40) Find the GCF 8 Factor the GCF out of the parenthesis 8(2x + 5) Check by distribution 8(2x + 5) = 16x + 40

Practice (9x + 27) 9(x + 3) (12x2 + 18x) 6x(2x + 3)
